Application filed March 25, 1909, Serial No. 485,802. Renewed December 14, 1911. Serial N 0. 665,750.

To all whom it may concern:

' Be it known that I, THoMAs F. PEARSON, a citizen of the United States, and resident of Billerica, county of Middlesex, and State 'of' Massachusetts, have made a new and useful Invention in Flying-Machines, of which a the following is a specification.

My invention is directed particularly to improvements in that type of flying-machines which are heavier than air, and it has for its object, to provide a novel means rounding air inwardly against the faces of, the vanes or blades of the screws, through the agency of a plurality of inclined rotatable surfaces or planes which surround the screws and are adapted to rotate in a reverse direction from the direction of rotation of such screws.

My invention will be fully understood by referring to the accompanying drawings, in which,

Figure 1 is a plan view of a flying-ma- "chineyembodying my improvements, showing also a driving engine supported by the frame of the entire machine. Fig. 2 is a front elevational view, as seen looking at Fig. 1 from the bottom toward the top of the drawings. Fig. 3 is a perspective view ofoneof the rotary frames within which the propelling'screw vanes or blades are secured; and, Fig. 4 is a similar view-of the means for bringing about the improved lift-' ing and propelling effects upon the vanes or blades of such screws orpropellers. Fig. .5 is a detail, part sectional, part side elevational view of 'the driving gearing and operative connections between the devices illustrated in Figs. 3 and 4; and, Fig. .6 is

a detail elevational view illustrating the manner of securing the driving gearing to the supporting frame of the machine.

Referring now to the drawings in detail, in all of which like numerals and letters of reference represent like or equivalent parts, 4 represents theframe of the machine consisting of a plurality of tubes made preferably of aluminum or very light metal and secured together so as to constitute a trussed structure of relatively great strength. 6 represents the propelling engine secured below the entire frame and operatively con nected by a belt with a driving pulley 14, carried by a driving shaft 11, journaled in the frame near its center at two points, 13, 13,.above the engine, and at its outer ends in hangers, the upper ends of which are connected directly to the bottom strin er of the frame. At the opposite ends of this frame there are provided pairs of journal bearings vertically alined and adapted to support rotary screw frames 2, which frames are constructed as shown in Fig. 3, preferably of light metal, such as aluminum, and provided each with a rotary shaft 12 and spirally disposed metalli pebands 8, there being two such bands for "each frame to which are attached the outer edges of two screw vanes or blades, the inner edges thereof being connected directly to the shafting, (see Fig. 2) so as'to constitute in each instance two complete screws or propellers, said frame being braced vertically and provided with the necessary radial end supporting arms, as clearly shown.

1 represents-a substantially rectangular frame constructed as shown in Fig. 4, so as to have four compartments, each open at its opposite ends and each inclosed on one side only, as-indicated by the letter a and in vertically disposed shaded lines, so as to constitute inclined rotatable surfaces or planes, this frame being supported at its opposite ends, as clearly shown,-by a hollow or tubular shaft 5 which surrounds the shaft 12, 3, 3, constituting hubs for securing the frame directly to the shaft. Each of these hubs is providedwith a gear-wheel The shaft 11 is geared at its opposite ends through bevel gear-wheels 16, 16 with corres ondin bevel ear-wheels 17 17 which p b b a gear-wheels in turn drive corresponding pairs of bevel gear-wheels 18, 18 connected to the opposite ends of the shafting 12, through the agency of idle bevel gear-wheels 19, 19, which in turn drive the bevel gearwheels 20, 20. Both sets of gear-wheels and their interconnected shafting are secured directly to the frame by set-screws 10 extending through openings 9 in the enlargements at the ends ofsaid frames, and the entire arrangement is such that through the agency of these interconnected gear-wheels reverse motions are given to the screws and the surrounding frames.

On examination of Fig. 1 it will be seen that when the apparatus is set in motion the screws in the cylindrical frames 2 will. be

given rotation as indicated by the inner set of tailless arrows in a direction from left to right. It will also be seen that the rotary frames 1' will be given a reverse rotation as indicated by the outer set of tailless arrows from right to left, so that the indrawn air, as indicated by the enlar edtailed arrows in both instances, will be forced in through the open faces 7 of the frames (see Fig. 4) by the inclined rotary surfaces at, a (see also Fig. 4:) thereby tending to condense the same in such manner as to give to the rotary screws which are moving in reverse direction a much greater lifting efiect.

It will be understood, of course, that such a machine may be provided with well known forms of air supporting wings, steering devices and means such as aregenerally in use for varying the elevation of the machine and that a seat may be provided for the operator at any desired point upon the frame, accessible to the engine and control apparatus, such matters coming well within the" skill of those versed in the art, my improvement herein described being directed broadly to the application of a principle which I believe to be new with me.

I do not limit. my improvement to the especial details of construction shown in the drawings; nor to any definite number or arrangement of such combined screws or propellers and rotary air compressing frames,

as these may be utilized in any. preferred manner, either singly or any plurality of such combined parts may be utilized, the essence of my invention lying in the producing of an increased lifting and propelling effect because of the fact that the rotatable surfaces which are rotated reversely to the direction of the screw cause the air 1 through which the screw is being rotated to Having thus described my invention what adapted to rotate in one direction; in combination with a plurality of inclined rotatable surfaces or planes surrounding said screw or propeller and provided with means for rotating them in a reverse direction to that of the screw, the rotatable surfaces being so located that they will, when in motion, concentrate or condense the medium upon which they act about the vanes or blades of the screw or propeller, substantially as described.

2. A flying-machine embracing a' frame; a driving motor therefor; a screw or propeller secured thereto; in combination with a plurality of inclined rotatable surfaces or planes surrounding the screw and provided with means for rotating them in a reverse direction to that of the screw, the rotatable surfaces being so located that they will, when in motion, concentrate or condense the medium upon which they act about the vanes or blades of the screw or propeller, substantially as described.

3. A flying-machine embracing a frame;

a motor secured therein; a plurality of pro-- and operatively connected with the same motor through mechanism adapted to retate them in reverse directions, the rotatable surfaces being so located that they will, when in motion, concentrate or condense the medium upon which they act aboutthe vanes or blades of the screws or propellers, substantially as described.

4=. A flying-machine embracing a frame; a'propelling motor secured therein; a pair of lifting screws located at opposite ends ofthe frame and geared to the motor; a plurality of inclined rotatable surfaces or planes located around each one of the lifting screws and geared also to the same motor through mechanism adapted to rotate them in reverse directions, the rotatable surfaces being so located that they will, when in motion, con centrate or condense the medium upon which they act about the vanes or blades of the screws or propellers, substantially as described.

5. A flying-machine embracing a frame; a motor suspended beneath the same a pair of lifting propelling screws operatively journaled at the opposite ends of the frame and with their rotatable shafts extending in a vertical direction; 'a plurality of inclined rotatable surfaces surrounding each screw or propeller; the rotatable surfaces and the screws being geared directly to the motor through mechanism adapted to-rotate them in reverse directions, the inclined and pronoeasev a pelling efiect' of the rotatable surfaces in name to this specification in the presence of each instance being such as to concentrate twohsubscribing witnesses. the medium upon which they and the screws THOMAS F. PEARSON. act about the vanes or blades of such screws, Witnesses: 5 substantially as described. 'BURNETT B. HART, In testimony whereof I have signed my 7 Z. I. BISSONNETTE.
